CHAIR CONSTRUQTION Filed April 23 1945 2 Sheets-Sheet 2 INVENTOR.

Patented Feb. 18, 1947 UNITED STATE Another object of the invention is to provide a base pan to receive the molded wire fabric or wire screen, which may be either a seat or a back rest, and means for securing the pan in place in the structure of the chair.

With the above and other objects in view, the invention comprises certain new and useful constructions, combinations and arrangements of parts, clearly described in the following specification, and fully illustrated in the accompanying drawings, in which:

Fig. 12 is a transverse sectional view through a modified form of the seat construction.

Referring to the accompanying drawings, which illustrate the practical embodiment of the invention, 5 designates one side frame member of a chair for public places or theatres, and 6 the companion side frame member. The side member 5 is provided with a base 8 and the side frame member 6 is provided with a base 1, the two bases being connected to each other by means of the tie member 9.

The side frame member 5 is provided with a bracket arm Ii), to which the connecting side plate H is pivoted by the stud pin I2. The side plate H is provided with a marginal flange Ila, which serves to reinforce the plate, and the upper portion of this plate and its flange are disposed in an approximately straight line. The side frame member 6 is provided with a. bracket arm l3, to which the side plate I4 is pivoted by the stud pin l5, and the side plate i4 is provided with a marginal reinforcing flange Ma, and is similar in shape and general construction to the side plate H. One of these side plates is a right member and the other is a left member of the chair seat assembly.

The chair seat comprises the base pan l 6, which has a main wall I! and a marginal flang IS, The main wall I1 is formed with openings l9 and 2t, located on opposite sides thereof, which are adapted to receive the straight edge portions H and Id of the side connecting or supporting plates II and It.

The seat pan i6 is constructed to snugly receive the molded seat member at, which is constructed of woven wire or screen material, which may be made from aluminum, aluminum alloy, stainless steel, bronze or other wire, machine woven to form a screen of substantially closed mesh, or small mesh openings, depending on the requirements of the trade.

The screen material of which the seat member 2i is constructed is molded to provide a relatively deep marginal flange 22, the lower edges 23 of which are disposed in a common plane, so as to have equal bearing on the main wall I! of the base pan i6, and within the marginal flange l8 thereof. This marginal pan flange prevents outward displacement of the Wire ends of the screen, and a binding ring or loop 24 is welded or otherwise united to the lower edge portions of the flange 22, to prevent inward displacement of the wire ends.

The seat member 2| is molded with rounded marginal portions Zia, which provide smooth bearing surfaces for the comfortable sliding movement of the user thereon, and also provide resilient bends between the upper main wall 2!?) of the seat member and its supporting flange 22. When any load is imposed upon the main wall Zlb thewires which compose this wall will be placed under tension, while the wires of the rounded marginal portions Zia and the flange 22 will be placed under bending stresses.

In order to positively couple the wire screen seat member 2! to the side plates II and i i, angle bars 25 and 26 are welded against the sides of the frame loop 24, thereby providing bottom flanges 25a and 26a, which are bolted directly to the straight edge portions H and M of the side plates H and I4, through the openings It and 20 or the pan [6, as shown in Fig. 4. In this way: the entirezseat assembly, is rigidly connectedtothe side plates H and' it; while these plates have a moderate pivotal movement on the supporting brackets i and It.

Should it be desired to cover the screen fabric seat member 2! with upholstery the faCingteX- tile fabric material may be tucked under: the projecting wire ends of the side flange 22 of the seat member, which will provide an effectivegrip on the marginal portions of the fabric. GOV?" ering which may e employed.

By dispensing. with the use of upholstery Work, the entire seat assembly provides" a self ventilating support-of great flexibility andhav ing. an exceedingly comfortable. cushioning action,

The frame side member 5 is provided with a. rearwardly projecting spherical headed stud 21 carried by the plate '28, and the frame'side memher 6' is. provided with a' spherical. headed stud 29, carried by, plate.3il2

The ball headedstudsli; and29.of the side frame members or the chair, are. adapted to enter the keyhole slots Z'i'aand 2% formed in the base pan 3l'of' the backrest assembly. This pan is constructed with a marginal flange 32.. which extends along. thesides and upper edge thereof, but not along the bottom edge of" the pan.. Against the main wall 33 of this'pan the marginallflange 3d of thescreen fabric back rest 35 is disposedthe flange 3'4Lof thisscreen; fabric. back rest; being confined by theflange. 32': ofithe pan 3!.

Withinthe back rest.3.5j the UT-shapedmetal bars 35; Hand 38 are secured at their ends, as. by welding to the marginal flange 3 3 of this back rest, ,inparallelirelation. to eachother.

The uppermost bar 35. is engagedlby the angie bar 39,,whichisweld'ed. or otherwise. securedto the main wall 331 ofthe. base. pan 3i,.and the two members; that .is,.the pan 3Iiand'thescreen back rest 35, arethus coupledtogether.

The pan 3'! is formed with a struckein portion 4d, located on one. side, thereof, which provides a smallopening demand; another struckei'n portio11-4l,.vvhich provides a smalliopening 41a. A. metal tube :2 is. slidabiy mounted between the lower cross bars 3! and. 38iof"the back rest and. the inner surface of" the main wall 33'. of the pan 3]. The upper'end' of the metali tube 42 engages the struck-inportion 43. Inthis tube a glass or other form of'a tubular container G3'is inserted; to receive through the opening 4321. match ends, ashes from cigarettes and, cigars,. and ends of the same.

Another metal tube: "isslidably mounted to engage thestruck-in portion-41', and'within this tube. a tubular waste. container is inserted through the lower endthereof.

' The entire. back. assembly may be detached fromv the sideframe. members of. the chair, by. disengaging the ballfheaded studs i'i'and 29 from the keyhole. slots ZTa andj 29a of the base pan S'I, asby. a liftingmotion of the backfassembly.

In. Fig. 121 a modified. form of the seat construction. isshown, wherein the basev pan. 501' is shown to have a concave-convex main wall 51,

against the flange thereof,

and a marginal flange 52. One side 52a of this marginal flange is inclined outwardly and upwardly, so that the forward edge of the wall 5| will be located rearwardly of the upper edge of the flange. The screen fabric seat member 53 is constructed with the usual marginal flange 54, which is stiffened by the inner ring frame 55, and this marginal flange is nested against the marginal flange 52.of;the-pan 5E; The forward side Ma of. the marginal fl'angebf. is inclined downwardly and rearwardly, so that the rounded portion of the molded screen fabric seat member 53 will overlie the upper edge of the pan flangeS-E.

Thisconstruction also serves to minimize the total area which the complete chair will occupy in atheatre, and thereby tends to provide a slight-aislespace increase between adjacent rows of the theatre.

In.the seat and in. the back assemblies, a metal screenfabrimwhichis molded to a pan-like form ofbody, provides the external wear. surface which is engaged by the garmentof. the user,.and also provides the cushionwhich affords a comfortable support forv the body of. the. user. This cushion develops from the. resilient character. of the screen fabric. and. the dished formation of the same.

In both. cases an uncovered screen. fabric cushion provides maximum. ventilationand cooling, and fullest ventilation.

Whenrust resisting metal. is. employed. it is easy to completely clean a theatre; chair, by air blast, or washing.

It is understood that-theeseatfandback-rest construction :may; be applied; to any. type. of. chair or. furniture construction; and that. variouschangesirrthe details of. construction, theselection and use of all available-materials, and the combinationand arrangement, of. such materials in the construction disclosed; mayybemade, within the limits oftherinventinn; asdeflned bythe claims hereof.
